on ubuntu 20.04 (focal) with BCM43142 wifi After updating the system, specifically the kernel from version 5.15.0-73 to 5.15.0-74, the wifi stopped functioning correctly. The network is detected, but it cannot connect. When loading the previous kernel 5.15.0-73, everything works as before.
ps 5.15.0-75 works fine. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2020393 Title: Jammy update: v5.15.102 upstream stable release Status in linux package in Ubuntu: Invalid Status in linux source package in Jammy: In Progress Bug description: SRU Justification Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from a mainline/stable Linux tree or a minimally backported form of that patch.
